Technical Field
[0001] The utility model relates to the technical field of filter press processing, and more specifically to a welding tool for an outer frame of a filter press. Background Art
[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a liquid, causing it to seep out. It's a commonly used solid-liquid separation device. It was first used in chemical production in the early 18th century and remains widely used in industries such as chemicals, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection. The main housing of a filter press is supported by a frame, which is typically welded, for example, with two supporting legs and a central crossbar welded together to create a stable structure.
[0003] Some existing filter press outer frame welding methods involve manually supporting the workpiece and then welding manually. This method can lead to unstable workpiece docking during the welding process, thereby reducing the welding quality of the product. Therefore, to solve this problem, we have proposed a filter press outer frame welding tool. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a filter press outer frame welding tool, which adopts the following technical solutions:
[0005] A welding tool for the outer layer frame of a filter press comprises a base, a mounting box is fixedly installed on one side of the base, a mounting slot is opened in the base, two symmetrically distributed movable plates are slidably installed on the top of the base, a clamping assembly is provided at the top of the two movable plates, a driving assembly is provided between the two movable plates and the base, a support plate is provided above the base, two symmetrically distributed second cylinders are provided at the top of the base, the ends of the two second cylinder piston shafts are fixedly connected to the bottom of the support plate, a limit assembly is provided on the top of the support plate, linear motor modules are provided on both sides of the base, mechanical arms are provided at the tops of the moving modules of the two linear motor modules, and welding guns are provided at the ends of the two mechanical arms.
[0006] By adopting the above technical solution, when the equipment is used, the staff will place the two frame columns above the two movable plates respectively, and then fix the frame columns through the clamping components. When the frame columns are fixed, the staff will place the cross bar above the support plate. A limit component is provided above the support plate, which can limit the positioning of the cross bar, so that the frame columns and the cross bar can be stably connected. When the cross bar is limited, the support plate and the cross bar can be driven to rise synchronously by the second cylinder to adjust the height of the cross bar, so that the cross bar can be installed at different positions between the two frame columns. When the frame columns and the cross bar are clamped, the staff will place the cross bar above the support plate. The driving assembly drives the two movable plates to move relative to each other, and the two movable plates move with the same-side frame columns, so that the two frame columns are in contact with the opposite side of the cross bar, which can play a role in docking, which is beneficial to improving the stability and accuracy of product docking. Subsequently, the welding gun on the same side can be driven by the robotic arm to move to weld the product. The cooperation of the two sets of robotic arms and welding guns is beneficial to improve the welding efficiency of the equipment, and the linear motor module is used to drive the same-side robotic arm and welding gun to move, so as to achieve the effect of adjusting the position of the robotic arm and welding gun, which is convenient for the equipment to weld the product at multiple angles, which is beneficial to improve the welding efficiency of the product.
[0007] Furthermore, the clamping assembly includes two first support plates fixedly installed on the top of the movable plate, and the two first support plates on the same side are symmetrically distributed at the top of the movable plate in the same group. Telescopic rods are fixedly installed on the opposite sides of the two first support plates, and splints are fixedly installed on the ends of the two telescopic rods, and stabilizing plates are fixedly installed on the tops of the splints.
[0008] By adopting the above technical solution, the staff places the rack column above the movable plate, and then drives the same-side clamping plate to move through the telescopic rod. The cooperation of the two clamping plates can clamp and fix the rack column, and a stabilizing plate is provided on the top of the clamping plate. The stabilizing plate contacts the opposite side of the rack column, which plays a role in balancing and stabilizing the rack column, which is conducive to maintaining the stability of the placement of the rack column.
[0009] Furthermore, the driving assembly includes a double-thread screw rotatably installed in the installation groove, and the side wall of the double-thread screw is provided with two symmetrically distributed support blocks. The top ends of the two support blocks slide through the installation groove, and the top ends of the two support blocks are fixedly connected to the bottom end of the movable plate on the same side. A reduction motor is fixedly installed in the installation box, and one end of the double-thread screw passes through the installation box and is fixedly connected to the end of the output shaft of the reduction motor.
[0010] By adopting the above technical solution, the double-thread screw is driven to rotate by the reduction motor, and the double-thread screw is used to drive the two support blocks to move synchronously. The support blocks move with the movable plate and the frame column on the same side, which facilitates the docking of the frame column and the cross bar.
[0011] Furthermore, limit blocks are fixedly installed on both sides of the two support blocks, and the inner wall of the installation groove is provided with a limit groove matching the limit block on the same side. Two symmetrically distributed balance blocks are fixedly installed on the bottom ends of the two movable plates, and a groove matching the balance block is provided on the top of the base.
[0012] By adopting the above technical solution, when the two support blocks are located in the installation grooves and slide, the two support blocks slide with the limit blocks in the limit grooves on the same side. The cooperation between the limit blocks and the limit grooves is conducive to improving the stability of the sliding of the support blocks, and when the support blocks drive the movable plate on the same side to move, the movable plate slides with the balance block in the groove on the same side. The cooperation between the balance block and the groove is conducive to maintaining the stability of the sliding of the movable plate, and thus is conducive to improving the accuracy of the contact between the rack column and the cross bar.
[0013] Furthermore, the limiting assembly includes two second support plates fixedly installed on the top of the support plate, and pillars are fixedly installed on the opposite sides of the two second support plates. A movable groove is opened on the opposite sides of the two pillars, and support rods are slidably installed in the two movable grooves. Springs are fixedly connected between the opposite ends of the two support rods and the inner wall of the opposite side of the movable groove on the same side, and limiting plates are fixedly installed on the opposite ends of the two support rods.
[0014] By adopting the above technical solution, the staff places the cross bar above the support plate, and the cross bar pushes the two limit plates. The limit plates push the support rods on the same side to slide in the movable grooves on the same side, and the support rods push the springs on the same side. The springs give the limit plates on the same side a rebound force. Through the cooperation of the springs, support rods and limit plates, the role of limiting the positioning cross bar is played.
[0015] Furthermore, two symmetrically distributed sliding blocks are fixedly mounted on the side walls at opposite ends of the two support rods, and the inner walls of the two movable grooves are provided with sliding grooves that match the sliding blocks on the same side.
[0016] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod slides with the slider in the sliding groove on the same side. The cooperation between the slider and the sliding groove is conducive to maintaining the stability of the support rod sliding and helps to prevent the support rod from leaving the movable groove.
[0017] Furthermore, mounting plates are fixedly installed on opposite sides of the two movable plates, and the cross-sections of the two mounting plates are both "L"-shaped. First cylinders are fixedly installed on opposite sides of the vertical sections of the two mounting plates, and the piston shafts of the two first cylinders slide through the mounting plates on the same side, and positioning plates are fixedly installed on the ends of the piston shafts of the two first cylinders.
[0018] By adopting the above technical solution, when the two rack columns come into contact with the cross bar, the first cylinder pushes the positioning plate on the same side, so that the positioning plate comes into contact with the opposite side of the rack column on the same side. Through the cooperation of the two groups of first cylinders and the positioning plates, the two rack columns are squeezed, which is conducive to maintaining the stability of the contact between the rack columns and the cross bar.
[0019] In summary, the present invention has the following beneficial technical effects:
[0020] (1) In the present invention, the clamping assembly is provided to clamp and fix the frame column, and then the cross bar is supported by the support plate. A limit assembly is provided on the top of the support plate to limit and fix the cross bar, so that the frame column and the side opposite to the cross bar can be stably contacted, which is convenient for subsequent welding and helps to improve the welding quality of the product.
[0021] (2) In the present invention, after the two frame columns are in contact with the cross bar, the first cylinder pushes the positioning plate on the same side to move and contact the side opposite to the frame column on the same side. The positioning plate pushes the frame column, which facilitates the stable fit between the frame column and the cross bar, and is beneficial to improving the subsequent welding quality and efficiency of the product.

[0036] Limit blocks are fixedly installed on both sides of the two support blocks 23, and a limit groove matching the limit block on the same side is opened on the inner wall of the installation groove 3.
